Home to Metro Nashville — Tennessee's capital and largest city — Davidson County operates as a consolidated Metro government with a distinct fee structure that sets it apart from every other county in the state.
Davidson County is home to an estimated 715,000 residents as of 2024 — making it the most populous county in Tennessee and one of the fastest-growing major metros in the United States. Unlike every other county in this resource, Davidson County operates under a consolidated Metro government that merged the City of Nashville with Davidson County in 1963. As a result, there is no separate county government, and all development regulation, permitting, and fee collection flows through Metro Nashville — specifically the Metro Codes Administration.
The county contains approximately 314,000 housing units, with median home values near $475,000 as of 2024 — reflecting sustained in-migration, limited land availability, and strong employment anchored by healthcare, higher education, and entertainment industries. Average new single-family homes in Davidson County span approximately 1,850 square feet, skewed lower by the prevalence of infill construction, attached townhomes, and urban product types common in Nashville's growth corridors.
Davidson County does not levy an Adequate Facilities Tax or any equivalent county-level privilege tax on new residential development. Metro Nashville's primary cost-of-development charge on new construction is the Metro Codes building permit fee, which is calculated using ICC Building Valuation Data applied to project square footage and occupancy classification — a methodology tied directly to construction cost estimates rather than a fixed per-square-foot rate. There is no separate school impact fee or infrastructure privilege tax collected at permit issuance. Builders operating in Davidson County therefore face a meaningfully different — and generally lower — county-level fee burden than those working in adjacent Williamson, Rutherford, Williamson, Wilson, Sumner, or Maury counties, though Metro's permitting complexity and land costs remain significant project variables.

Local reporting and public records covering Davidson County's development fee landscape, housing supply debate, and growth policy.
Metro Council Member Tasha Ellis proposed shifting Nashville's infrastructure funding burden from property taxpayers to developers through impact fees and real estate transfer taxes. Davidson County faces $15.5 billion in infrastructure needs through 2028 — roughly 20% of the state's total — while Metro's current budget covers just 1% of what's needed.
Read MoreThe Beacon Center filed a class action lawsuit against Metro Nashville challenging its $0.71/sq ft stormwater capacity fee — enacted January 1, 2024 and charged at permit issuance. The suit argued the fee unconstitutionally placed the cost of public infrastructure solely on those seeking building permits, and calculated charges on total post-development impervious area rather than net new area added.
Read MoreMetro Codes Administration has implemented process improvements aimed at reducing residential permit review timelines, which had drawn criticism from builders as Nashville's construction boom placed unprecedented demand on the department. The streamlining effort reflects Metro's recognition that permitting speed — not just fee levels — is a material variable in Nashville development project economics.
